[jira] Commented: (SMX4NMR-233) NMR should block if target service is unavailable to facilitate lazy init of services and/or temporary abscence of a service.

Geert Schuring commented on SMX4NMR-233:
----------------------------------------

When using clustering this already happens as the request message remains in the message queue until a client processes it. I agree that the NMR should behave similarly when only local endpoints are used.

> Right now, if you use the NMR within ServiceMix 4 (I'm using 4.3 FUSE), an invocation on a service that is not registered on the NMR will fail immediately. It would be better if it did not fail, but block for a period of time (say 30 seconds, similar to the delay on an OSGi service in blueprint / Spring DM) and only fail if the target has not returned in the delay period. This way we can handle temporary outages of backend services and service updates.
